Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 22 points:

(4,6)(7,8)(9,13)(10,14)(11,12)(16,19)(20,22);(4,6)(8,12)(10,13)(15,16)(17,20)(18,19)(21,22);(7,9)(8,13)(10,12)(11,14)(16,19)(17,21);(7,9)(8,13)(10,12)(11,14)(15,16)(17,22)(18,19)(20,21);(1,2);(7,9)(8,13)(10,12)(11,14);(3,4)(5,6)(7,10,11,13)(8,14,12,9)(15,17)(16,20)(18,21)(19,22)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((4,6)(7,8)(9,13)(10,14)(11,12)(16,19)(20,22), (4,6)(8,12)(10,13)(15,16)(17,20)(18,19)(21,22), (7,9)(8,13)(10,12)(11,14)(16,19)(17,21), (7,9)(8,13)(10,12)(11,14)(15,16)(17,22)(18,19)(20,21), (1,2), (7,9)(8,13)(10,12)(11,14), (3,4)(5,6)(7,10,11,13)(8,14,12,9)(15,17)(16,20)(18,21)(19,22));
